Application filed January 18. 1902. Serial No. 90.353.

To all IIIIIIIII i/ may concern:

Be it known that we, (n.uniss W. (RAMER I. I I

and HARRY llaait, citizens of the United I States, residing at 938 Webster avenue, Scranton, in the county of Lackawanna and Statev of Pennsylvania, have invented certain new and useful lm )rovements in Motors; and we do hereby dcciare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in fmotors, and more )articularly to a form of motor designed to e applied to a washingtub.

It consists in certain novel constructions, combinations, and arrangements of arts, as will hereinafter be more fully descrl ed and claimed.

'In the accompanying drawings, Figure 1 represents an inverted plan view of a tub with the present improved motor applied thereto, the supporting-legs bein shown in section. Fig. 2 re' resents a top p an-view of the motor, parts eing shown in horizontal section in order to more clearly disclose the entire structure. Fig. 3 represents a transverse vertical section through the tub-supporting frame and a part of' its operating mechanism, the cylinder and supportin -legs of the tub being shown in elevation ig. 4 represents an enlarged detail perspective view of the pressure-governing valve and its easing. Fig. 5 represents a transverse vertical sectionthrough said valve and easing, the valve being set to communicate with one end of the cylinder. Fig. 6 represents a similar view of the same with the valve set to communicate with the opposite end of said the tub, and to accomplish this result to the.

best advantage and in orderto attain other desirable ends we employ, as seen in the accompanying drawings, in cor-section with r l l i i any preferable form of tub I and suitable supporting-legs 2 L, a castin 3, formed with radially-projecting arms 4 4, being secured to said tub I by any preferred means, as screws 5 5 and a threaded upwardly-projecting lug (3, designed to be threaded centrally in the bottom of the tub I. Projecting downwardly from the castin 3 and formed integral therewith is a suitable shaft '7, extending in the same vertical plane with lug 6 and being de signed to be passed through a center well of the supporting-casing 8, which casing incloses the legs 2 and tirml holds the same in position. A not 9 is pre crably threaded on the lower end of the said shaft 7 for retaining the same in position. Surrounding the shaft 7 and preferably engaging an annular shoulder intermediate the length thereof is a suitable cone l(),which cone is designed to engage ball or other suitable antifriction-bearings 11, the said bearings running in any preferred or well-known form ofcup 12, the said cup preferably being supported by the center or well portion of the casing S. It will thus be seen that the tub is mounted and rotated freely and with a minimum friction. A collar 13 surrounds the shaft 7 above the. cone 10 and carries a second collar 14 spaced therefrom and formed inte rally therewith at its lower end, the outer cdilar 14 only partially inclosing the inner collar 13, the said collar 14 being concentric with the collar 13 for less than one hundred and eighty de rees, each end being straight for the remainder of its length, as best seenin Fig. '2 of the drawings. It will be seen that the construction of the two collars 13 and 14, spaced apart and formed inte 'ral with each other, provides a suitable welT 5 ring 15, designed to be retained between t to two collars and have its free ends 16 and 17 extending beyond the flared portions of collar 14 for purposes hereinafter mentioned, suitable lugsM 14 extending inwardly from said flared portion for retaining said s ring in position. Also formed integrally wit 1 the base of collars 13 and 14 is a segmental rack 18, provided with outwardly- )rojecting teeth 19 and formed with a suita )le web 20 and provided with a se mental slot 21, designed to be engaged by t to head of a scrcw as 22, secured in one of the legs, whereby the web 20 will be guided and prevented from having lateral movement. Asuitablc segmental slot for the reception of the coiled I ]purposes 21 is formed in that portion of web extending beyond the flare of the collar 14, and any suitable lug, as 22, projects upwi'ndly from one of the legs 2 into said slot for limiting the length of stroke of rack 18. i A straight rack-bar 23 is provided and formed with teeth designed to mesh with. teeth 19, the said bar being secured to a pist0nrod 24, carrying the head 25, within a suitable cylinder 26, whereby movement of the piston is designed to move segmental rack 19, suitable pressuresupply pipes 27 and 28 communicating with the opposite ends of cylinder 26 for operating the piston within said cylinder, the supply ofpressure being controlled by a suitable valve 29. Said valve 29 is inclosed in a suitable casing 30 and is provided with a three-way bore having an opening 31 and openings 32 and 33, the opening 31 being designed at all times to communicate with an enlargement 34 of the valve-casing 30, which enlar ement is connected with a suitable supply-pipe 35, designed to supply pressure to the valve, said pressure being in the form of water, steam, compressed air, or any other suitable motive fluid. The openings 32-and 33 are designed to be brought alternately into register with the enlargements 36 and 37, respectively, of the valve-casing 30, the said enlargements preferably extendin longitudinally of the valve-casing for a suitable distance and each bein formed with a laterally-projecting tube 38, the said tube being secured to its respective pipe 27 or 28 by means of any suitable inclosing nut 39. The rear portion of valve 29 is provided with an enlarged transverselyarranged bore 40, designed to communicate at all times at its lower end with enlargement 41, formed in the casin 30, and communicatin with any suitabe tube 42 for hereinafter mentioned, the said ore having its upper end brought alternately into register with enlargements 36 and 37, respectively, as indicated in dotted lines ih Figs. 5 and'6. It will be seen by ref erence to these two figures that when the opening 32 is registering with enlargement 36 the upper end of bore 40 is registering with enlargement 37, and when opemn g 33 in register with the enlargement 37 said upper end of the bore 40 will register with enlargement "36, those alternate registrations being accoinplished by oscillations of the valve 29 by means hereinafter set forth. in order to retain valve 29 snugly in its position in its casing, we preferably surround the stem of said valve with a su'tablc spring pressing the said valve at ono cnd and a washer l4 surrounding the sanbvalvc-stcni at the other end,

" whereby tlic'valvo is cushioned against longitudinal displacement. Any suitable cap may be threaded on the outer end of casing 30 for closing the same, the wasl'ier 4 ipreferablyresting against suitable packing 1 erases interposed between the same and said cap, as seen in Fig. 2, the said on i being apertured centrally for the passage 0 tliestein of valve 29. Rigidly secured to the outcr cnd of the stem of said valve .39 is a laterallyprojccting arm 46, provided at its outer; end witii lugs 47 and 48. The lugs 47 and 48 extend injdifferent vertical planes, so that an arm moving in one vertical plane may strike one of said lugs and swing arm 46 in one direction and another arm moving in another vertical plane may strike the other lug and swing the arm 46 in an opposite direction, whereby the os cillatin movement of the valve 27 may be accomp ished.

'The casting 3 is formed, preferably, with downwardly-extending lugs 49 and 50, which engage the bent ends 16 and 17, respectively, of the spring 15, whereby movement of the segment 18 is designed to move said casting 3 and the tub 1, carried thereby. Downwardly-depending lugs 51 52 are carried by two of the arms 4, the said lugs being spaced at diflerentdistances from the pivot-point of the casting 3, so to move in diii'erent circular lines and pot tioned for engaging lugs 4-7 and 18, respectively, as they alternately brought into contact therewith by the movement of said tub. Screw 53 is preferably threaded in the end of cylinder 26 and is designed to be removed for introducing lubricant thereto.

In the operation of our improved motor power is supplied to connection 35, passed through front bore of valve 29 either into pipe 27 or 28, and moves piston-head 25 to the opposite end of the cylinder 26 to that at which it is at the time of starting, and during said movement rack 23 operates se ment 18 through the medium of spring 15 and its ends 16 and 1.7, communicating motion to lugs 49 and 50, swings the tub in one direction, brings one of the lugs 51 or 52 into contact with its respective lug at? or 48, throwing the valve 29 to an op osite position to that formerly assumed, w ereby the pressure' will be caused to enter the op ositepipe 27 or 28 to that formerly entered? the bore 40 b eing brought into register with the pipe formerly employed for eommuniceiting the power mehead 25 to move bac c to its former position, and the former active pressure is exhausted through bore 40, and the casting 3 swings about again and brings its ing51or52into register with its correspondinglug 4:7 or as,

and the operation is a zu'n repeated. This eporation may be continued as long nod, the pipes 27 and 28 being alternately as supply-pipes for a power medium and as exhaust-pipes, the valve 29 being alternately swung, as described, so that its here will be properly brought lnto register with the con erases nection of the said pipes for causing them to becorneactive or passive, as required for producing the desired result.

It will be seen from the foregoing that a cushioned oscillating movementof the tub will be produced, the spring 15 conveying the movement from the motor to the tub, thereby cushioning said movement, said spring tightening and recoil ing at each stroke of the piston-r0 24.

The front head of cylinder 26, through which piston-rod 24 passes, is removabl-y threaded into the end of the cylinder and is provided with a packingchamber 2% about said piston and formed with 3.1? irwardlyprojecting cone 24", surrounding said pistonrod for preventing to some extent admission of pressure to the packing within said chamhers. I

It will be seen by refe laterally-extending lug is iorrned u on arm is, designed to me in contact wit or just above the outer periphery of the front end of the valve-casing 30, and suitable lugs 55 are formed upon said valve-casing for limiting the movement of said arm 46, whereby the said valve cannot be thrown past a given position.

At times we find it desirable to lock the tub 1 against movement, and a form of lock is illustrated in the-accompanying drawings, in which 56 represents a suitable slide havin a preferably outwardly-bent portion 57, esigned to serve as a handle, and a downwardly-extending bar 58, designed to be passed between a pair of upwardly-extending preferably parallel plates 59, carried upon the cylinder 26. While-the bar 58 is moved nee to Fig. 4 that a out of contact with said plates the tub is free to oscillate. .We prefer to employ suitable brackets 60 60, inclosing the edges of slide 56 for supporting the same in position.

As best seen in Fig. 2, a suitable circumferential packing groove 39 is provided around the valve 29 and designed to contain any preferred form of packing-rim whereby the escape of pressure is prcventef As clearly seen in Figs. 1 and 2, the legs 2 are inclosed by suitable connected casings, which casings carry the oscillating valve and its case ant also carry the pipes 1.7 and 28 and cylinder 26 and all connecting parts be; tween said valve-casing, pipes, and the cylinder, a general frame being thus formed of which the cylinder .36 is a part, said framei'orming one head to the cylinder and the other head being in the 'l'oi'inof a lug (clearly seen in lrig. 2) threaded into anr removably secured within the end of the cylinder.

it is to be observed that the spring 15 not only serves the valuable function of cushioning the stroke of the tub or other frame actuated by the motor, but said sprin also has the advanta e of imparting to the tub or frame a relatively long stroke, even though a 'ing of the valve tendin pression and recoil materially increasing the swinging of the tub or frame. lt is further to be observed that while the spring 15 is coiled under the inertia of the tub or frame sul'hcient time is given for the exhausting of pressure from one end of the cylinder and the starting of the admission of pressure to the other end, which action obviates the possibility of back pressure in the cylinders, and thus prevents waste of power. The coiliu of the spring under the inertia of the tub alter the piston has arrived at the limit of the stroke permits of the lapse of sulliciciit time prior to the return stroke for permitting the accumulation of pressure on the opposite side of the piston from that previously acted upon. in other Words, when the tub is thrown in one direction by the pressure upon one side of the piston the tub continues to move after the piston has completed its stroke, and during such movement the valve is opened for releasing the pressure at one side of the piston and admitting pressure to the other side thereof, the opening and closto reduce thehnuximum pressure admitted to the cylinder until the pressure fluid has been permitted to accuniulate within the cylinder, and such accuinulation is permitted by the piston being left free to remain at rest momentarily during the continued stroke of the tub at the limit'of the stroke of the istoii. Thus when the tub returns sull'icieiitl y for permitting tlhe beginniii of the stroke of the piston the pressure on t 10 piston will be at the maximum or e ual to the pressure of the main supply. T hus the return stroke of the tub is given the benefit of the total pressure of the main supily. Of course many other advantages may be observed in the structure involving the cylinder, piston, and tub and spring, pcriiiitting a greater moveiiioiit of the tub than is imparted by the piston; but the above advantages are mentioned in order that the utility ol the present invdntioii may be understood, to such extent at least as to be"appreciated.

In this application we are not presenting claims covering the attaching of the oscillating frame to the actuating means by a fixedlyconiiectcd spring, such structure being covered by the claims of our co )cndiug application filed April 2, 1904, and ih-signatcd by Sorial No. 201,360.
